ANTISKIDDING DEVICE FOR WHEELS.

Specification 0:! Letters Patent.

Patented March 9', 1909.

Application filed April 1, 1908. Serial No. 424,512.

siding in the city and district. of Montreal,

in the Province of Quebec, Canada, have invented certain new and useful Improve-I ments in Antiskidding Devices for \Vheels; and I do hereby declare that the following is a full. clear, and exact description of the invention. such as will enable others skilled in the art to which itappertains to make and use the same.

The invention to be hereinafter described relates to vehicle wheels. and more particularl v to non-skidding devices for automobile wheels and the like.

Broadly speaking, the invention comprises fellies or tire seats adapted to be clamped together. and a non-skidding member movably mounted between the same and adapted to engage the surface of the roadbed over which the vehicle travels.

In order to more clearly disclose the construction, operation and use of the invention. reference should be had to the acconr pan ving drawings forming part of the present application.

'lhroughont the several views of the drawings, like reference characters designate the same parts.

In the drawings: Figure 1 is a side elevation. partly broken away; and. Fig. 2 is'* an edge view. partly in section.

Two complementarv t'ellies or tire seats 1 are provided, each being recessed as at 2 on its inner face. and provided with radial grooves 3 for the reception of spokes. \Vhcn clamped together by bolts or other suitable fasteuings. the recesses 2 of the fellies form an annular channel. in which is seated the springpressed yielding annular disk or plate 4. The width of the channel and the thickness of the disk 4 should be so proportioned as to allow the sides of the follies l to exert a slight frictional grip on the disk when the felliri'garc clamped tightly together. The springs 5, while supporting the disk, also allow a sli ht radial. movement of the same is the wlieel travels. -Thus, when the pneumatic tires are slightly compressed by the load pressure, the rim of the disk will be broughtinto contact with the roadbed, and a secure .hold will be given. absolutely preventing skidding or slipping of the tire in any direction. either forward. backward or sidewise. As shown in the drawings, the gripping edge of the disk is simply corrugated. It is evident. however, that this edge may be formed either with conical, pyramidal or any other form of gripping surface or teeth desired to prevent skidding or slipping of the wheel.

Many changes may be made in the constrnction and arrangement of the several pa rts, and many other combinations of these parts and substitutions for them may be had. without in any way departing from the field and scope of the present invention, and it is meant to include all such within this application, wherein only one preferred form of the invention has been shown and doscrihed.

Having thus fully described my invention, what I claim as new, and deside to secure by Letters Patent, i35 l A- vehicle wheel comprising two annular tire seats, each providedwith an annular recess and radial grooves and adapted to be clam ed togetherto. form an annular channel tierebetween, an annulardisk inovablymounted in said channel, and ,eprings for su porting said annulardlsk; a

n witness whereof Jhave hereunto set -my hand in the presence of two witnesses.
